SPECIFICATION forming part of Letters Patent No .-289,241, datedNovember 27, 1883. V Application filed April 28,1883. dSpecimens.) I

To all whom it may concern.-

Be it known that I, JARVIS B. EnsoN, of the town of Adams, in the countyof Berkshire and State of Massachusetts, have invented new and usefulImprovements in Pat- 1 ent-Leather and 2. ,Substitute Therefor, of

- those existing'in the substance knownby this iwliichthe following is aspecificitiou.

"This invention has for its object the production ;of an article whichresenrbles patentleather and possesses properties superior to term; audt-heinvcntion consists, first, in takingsheets of leather-such as aretechnically called T, splits, q'r those which are formed from the sidesof leather which have been sub-- jeetcd to the spliting proeess-andapplying upon the surface of thesame thin sheets of Lz'ylouite or asimilar substance of apropcr color, and which is applied by partiallydissolving the surface of the zylonite, or its equi valent, by any ofthe well-known solvents "of such'substances, and then subjecting thesame to pressure, as by a pair of rolls or any gradual] y progressing.eompressingsurface,

by which the leather and the zylonite will be united,zand then partiallydissolving or applying asolvent-sucli collod'ion--upon the exteriorsurface oftlie sheet of zylonite, and pri'igrcssivel y passing'itbetwrecua pair of rolls or compressiug-surfiice in contactwith a plateof glass or othcrsiiniiar surface, by which the exterior surface ofthcxylouiiewillibeasfinely polished as the surlnr-e against wf'ch it hasbeen compressed. A. convex shriie beginning at the center of the splitand gradually extending out to each end, in the caseof such articles asare formed from sides of leather. will'bc found to be the preferablemethod of an pi ying the pressure.

I do not broadly claim the method of coat- 40 ting leather with a.soluble, material, for this has been done before; but

that I do claim is-- 1. The method of makinga substitute forpatent-leather, consisting in partially dissolving the surface of asheet of zylonite or simi' Ian substance by a suitable sol-vent;secondly, applying the said sheet to the material forming the ,base,with the partially dissolved side of the'shcet'next thereto, and,thirdly, applying pressure to expel the surplus solvent and air, andcause an iutimateunion of the base and sheet of zylonit-e, substantiallyas and for the purpose described.

2. The method of making a substitute for patent-leather, consisting inpartially dissolving the surface of a sheet of Zylonite or similarsubstance andtsubsequently uniting said partially -dissolved surface tothe material forming the-base, and partially dissolving the exteriorsurface ofthc sheet of zylonitc and ,scribed my name and aflixcd my sealin the presence of two subscribing witnesses.
